and was about to enter the mouth of the harbor Sing Lee's eyes chanced to fall upon it. On the instant the old Chinaman was electrified into sudden and astounding action.
"Klick! Klick!" he cried, running toward Virginia. "Go b'low, klick."
"Why should I go below, Sing?" queried the girl, amazed by the demeanor of the cook.
"Klick! Klick!" he urged grasping her by the arm—half leading, half dragging her toward the companion-way. "Plilates! Mlalay plilates—Dyak plilates."
"Pirates!" gasped Virginia. "Oh Sing, what can we do?"
"You go b'low. Mebbyso Sing flighten 'em. Shoot cannon. Bling help. Maxon come klick. Bling men. Chase'm 'way," explained the Chinaman. "But plilates see 'em pletty white girl," he shrugged his shoulders and shook his head dubiously, "then old Sing no can flighten 'em 'way."
The girl shuddered, and crouching close behind Sing hurried below. A moment later she heard the boom of the old brass six pounder which for many years had graced the Ithaca's stern. In the bow Professor Maxon had mounted a modern machine gun, but this was quite beyond Sing's simple gunnery. The Chinaman had not taken the time to sight the ancient weapon carefully, but a gleeful smile lit his wrinkled, yellow face as he saw the splash of the ball where it struck the water almost at the side of the prahu.
Sing realized that the boat might contain friendly natives, but he had cruised these waters too many years to take chances. Better kill a hundred friends, he thought, than be captured by a single pirate.
At the shot the prahu slowed up, and a volley of musketry from her crew satisfied Sing that he had made no mistake in classifying her. Her fire fell short as did the ball from the small cannon mounted in her bow.
Virginia was watching the prahu from one of the cabin ports. She saw the momentary hesitation and confusion which followed Sing's first shot, and then to her dismay she saw the rowers bend to their oars again and the prahu move swiftly in the direction of the Ithaca.
It was apparent that the pirates had perceived the almost defenseless condition of the schooner. In a few minutes they would be swarming the deck, for poor old Sing would be entirely helpless to repel them. If Dr. von Horn were only there, thought the distracted girl. With the machine gun alone he might keep them off.
At the thought of the machine gun a sudden resolve gripped her. Why not man it herself? Von Horn had explained its mechanism to her in detail, and on one occasion had allowed her to operate it on the voyage from Singapore. With the thought came action. Running to the magazine she snatched up a feed-belt, and in another moment was on deck beside the astonished Sing.
The pirates were skimming rapidly across the smooth waters of the harbor, answering Sing's harmless shots with yells of derision and wild, savage war cries. There were, perhaps, fifty Dyaks and Malays—fierce, barbaric men; mostly naked to the waist, or with war-coats of brilliant colors. The savage headdress of the Dyaks, the long, narrow, decorated shields, the flashing blades of parang and kris sent a shudder through the girl, so close they seemed beneath the schooner's side.
"What do? What do?" cried Sing in consternation. "Go b'low. Klick!" But before he had finished his exhortation Virginia was racing toward the bow where the machine gun was mounted. Tearing the cover from it she swung the muzzle toward the pirate prahu, which by now was nearly within range above the vessel's side—a moment more and she would be too close to use the weapon upon the pirates.
Virginia was quick to perceive the necessity for haste, while the pirates at the same instant realized the menace of the new danger which confronted them. A score of muskets belched forth their missiles at the fearless girl behind the scant shield of the machine gun. Leaden pellets rained heavily upon her protection, or whizzed threateningly about her head—and then she got the gun into action.
At the rate of fifty a minute, a stream of projectiles tore into the bow of the prahu when suddenly a richly garbed Malay in the stern rose to his feet waving a white cloth upon the point of his kris. It was the Rajah Muda Saffir—he had seen the girl's face and at the sight of it the blood lust in his breast had been supplanted by another.
At sight of the emblem of peace Virginia ceased firing. She saw the tall Malay issue a few commands, the oarsmen bent to their work, the prahu came about, making off toward the harbor's entrance. At the same moment there was a shot from the shore followed by loud yelling, and the girl turned to see her father and von Horn pulling rapidly toward the Ithaca.

THE HEAVY CHEST
Virginia and Sing were compelled to narrate the adventure of the afternoon a dozen times. The Chinaman was at a loss to understand what had deterred the pirates at the very threshold of victory. Von Horn thought that they had seen the reinforcements embarking from the shore, but Sing explained that that was impossible since the Ithaca had been directly between them and the point at which the returning crew had entered the boats.
Virginia was positive that her fusillade had frightened them into a hasty retreat, but again Sing discouraged any such idea when he pointed to the fact that another instant would have carried the prahu close to the Ithaca's side and out of the machine gun's radius of action.
The old Chinaman was positive that the pirates had some ulterior motive for simulating defeat, and his long years of experience upon pirate infested waters gave weight to his opinion. The weak spot in his argument was his inability to suggest a reasonable motive. And so it was that for a long time they were left to futile conjecture as to the action that had saved them from a bloody encounter with these bloodthirsty sea wolves.
For a week the men were busy constructing the new camp, but never again was Virginia left without a sufficient guard for her protection. Von Horn was always needed at the work, for to him had fallen the entire direction of matters of importance that were at all of a practical nature. Professor Maxon wished to watch the building of the houses and the stockade, that he might offer such suggestions as he thought necessary, and again the girl noticed her father's comparative indifference to her welfare.
She had been shocked at his apathy at the time of the pirate attack, and chagrined that it should have been necessary for von Horn to have insisted upon a proper guard being left with her thereafter.
The nearer the approach of the time when he might enter again upon those experiments which had now been neglected for the better part of a year the more self absorbed and moody became the professor. At times he was scarcely civil to those about him, and never now did he have a pleasant word or a caress for the daughter who had been his whole life but a few short months before.
It often seemed to Virginia when she caught her father's eyes upon her that there was a gleam of dislike in them, as though he would have been glad to have been rid of her that she might not in any way embarrass or interfere with his work.
The camp was at last completed, and on a Saturday afternoon all the heavier articles from the ship had been transported to it. On the following Monday the balance of the goods was to be sent on shore and the party were to transfer their residence to their new quarters.
Late Sunday afternoon a small native boat was seen rounding the point
